我在我的app.js中使用自定义提供程序进行后端调用,然后在控制器中注入该提供程序并获得promise结果(我这样做是因为在每个控制器中调用getLoggedUser我只是从提供程序获得结果)和而不是做10个电话,例如我将在提供者中只做一个)。但我无法测试此提供程序$ get方法并且测试失败,因为从未进行后端调用。
我收到错误:
Error: Unexpected request: GET https://localhost:8443/user/current
app.js
angular.module('app', [
...
])
.config(config)
.run(run)
.controller('MainCtrl', MainCtrl)
.value('version', '1.1.0')
.provider('userProvider', function(){
this.$get = ['AuthenticationService',
function(AuthenticationService) {
return AuthenticationService.getLoggedUser();
}];
});
TEST
/* jshint undef:false*/
(function() {
'use strict';
describe('ListingController', function() {
var listingController, rootScope, scope, q, mockAuthenticationService, $httpBackend, service;
var provider = {};
var mockCurrentUser = {
id: 1782,
name: "One, Coordinator",
roleId: [
3, 10
],
eauthId: "coodinator1"
};
beforeEach(module('app'));
beforeEach(module('listing'));
beforeEach(function () {
module(function (userProviderProvider) {
provider = userProviderProvider;
});
});
beforeEach(inject(function($rootScope, $controller, $q, _$httpBackend_, _AuthenticationService_, userProvider, $injector) {
rootScope = $rootScope;
scope = rootScope.$new();
$httpBackend = _$httpBackend_;
q = $q;
mockAuthenticationService = _AuthenticationService_;
// provider = userProvider;
service = $injector.invoke(provider.$get);
rootScope.$digest();
listingController = $controller('ListingController', {
$scope : scope,
mockAuthenticationService : _AuthenticationService_
});
}));
describe('getLogged user and init',function(){
it("should call getLogged function", function() {
listingController.getLoggedUser();
rootScope.$digest();
expect(service).toHaveBeenCalled();
});
});
});
})();
控制器
function getLoggedUser() {
userProvider.then(function (data){
// Here I am getting result from back end call from provider which is good
});
如果我在提供者中做出类似的事情:
this.$get = function (AuthenticationService) {
return {
loggedUser : function() {
return AuthenticationService.getLoggedUser();
}
}
}
然后我可以在测试中做出类似的事情:
spyOn(provider , 'loggedUser').and.callFake(function() {
var deferred = q.defer();
deferred.resolve(mockCurrentUser);
return deferred.promise;
});
并且这将工作测试将通过,但是当我使用userProvider.loggedUser()时,在每个控件中使用这种方法。然后它将进行额外的后端调用,并且只有一次后端调用将进行。

如果我喜欢你建议调用服务,并且在方法调用getLoggedUser来自另一个服务,每次都会进行额外的调用...而不仅仅是像我没有功能的那样。
.provider('userProvider', function(){
return {
$get: function(AuthenticationService) {
return new userService(AuthenticationService);
}
}
});
服务
function userService(AuthenticationService) {
this.getLoggedUser = function() {
return AuthenticationService.getLoggedUser();
}
}
答案 0 :(得分:0)
这是基本结构:
$httpBackend.when('GET', 'localhost:8443/user/current').respond(200, /*optional response callback function*/);
$httpBackend.expect('GET', 'localhost:8443/user/current');
//here goes the function that makes the actual http request
$httpBackend.flush();
请务必定义您的httpBackend var - var httpBackend = $httpBackend;
。
而且为了检查服务是否已被调用,您必须使用间谍。
spyOn(service, 'method').and.callThrough();
//here goes the function that calls the service
expect(service.method).toHaveBeenCalled();
您将上面的两个块组合在一起,您应该能够达到您想要的效果。
describe('something',function(){
it("should do something", function() {
spyOn(service, 'method').and.callThrough();
$httpBackend.when('GET', 'localhost:8443/user/current').respond(200,/*optional response callback function*/);
$httpBackend.expect('GET', 'localhost:8443/user/current');
//call the function that makes http request and calls your service
rootScope.$digest();
$httpBackend.flush();
expect(service.method).toHaveBeenCalled();
});
});
关于您的服务:
function myService(){
var svc = this;
svc.myMethod = function(){
return someDataOrPromise;
}
}
